Abstract

Optical-feedback cavity-enhanced absorption spectroscopy is demonstrated in the mid-IR by using a quantum cascade laser (emitting at 4.46 μm ). The laser linewidth reduction and frequency locking by selective optical feedback from the resonant cavity field turns out to be particularly advantageous in this spectral range: It allows strong cavity transmission, which compensates for low light sensitivity, especially when using room-temperature detectors. We obtain a noise equivalent absorption coefficient of 3 × 10 9 /cm for 1 s averaging of spectra composed by 100 independent points. At 4.46 μm , this yields a detection limit of 35 parts in 10 12 by volume for N 2 O at 50 mbar , corresponding to 4 × 10 7 molecules / cm 3 , or still to 1 fmol in the sample volume.
